Abstract: 1,072,883. Radio rescue buoys. BURNDEPT ELECTRONICS Ltd. Nov. 26, 1965 [Nov. 27, 1964], No. 48440/64. Heading B7A. [Also in Division H4] A radio rescue beacon comprises a cylindrical buoy 10 having a rod aerial 30 projecting from its upper end plate 13, said aerial being mounted on a pivoted spring-loaded baseplate 32 so that it may be swung down alongside the buoy and be secured for stowing. The upper part 12 of the buoy 10 is watertight and contains the electronio components of a transistor transmitterreceiver and the lower part 18 contains a battery, which may be sea water-activated. A switch 38 operated by the baseplate 32 upon stowage of the aerial disconnects the battery, and in a similar way connection is made to the input/output terminal of the transmitterreceiver when the aerial is elevated. A pair of spring-loaded sheet metal paddles 40, 41, which are pivotally mounted on the buoy, are folded down for stowage, but project outwards when released, under the control of biasing springs 48, Fig. 3 (not shown). The said paddles provide stabilization for the buoy, downward movements of which in the water are strongly resisted, the paddles being fully opened with their inner edges firmly against the buoy, whereas upward movements are but little resisted, the paddles closing against the springs 48. A towing cord 52, Fig. 1, extending from a bridle 54, is used to lash the paddles 40, 41 and the aerial 30 to the buoy 10 for stowage, any surplus is taken up in a suitable reel, and it is then secured by a water-soluble fastening. The aerial 30 may have a flexible extension 31, Fig. 2 (not shown). In a second embodiment, three circular paddle blades 60, 61, 62, Fig. 4 (not shown), are mounted on the bottom closure 19 of the buoy and are arranged to fold inwards, by rotation on vertical axes, for stowing.

Title: Microwave oven control
IPC: G05D23/19
Filed: 1962-12-28
Abstract: 994,355. Control systems for microwave ovens. TAPPAN CO. Dec. 28, 1962 [June 14, 1962], No. 48891/62. Heading H2H. [Also in Division H5] The filament heating circuit of the magnetron 19 of a microwave oven is held energized for a predetermined period following the completion of a cooking period. Fig. 2 shows a control circuit in which the supply to the magnetron filament from terminals 23, 24 is connected via a normally-open switch 25 which is closed by energization of a relay coil 55 supplied from terminals 28, 29 through a rectifier 36. This energization is effected by opening and closing the oven door whose arm, Fig. 1 (not shown), momentarily closes a switch 18 thereby shortcircuiting a resistance 52 and connecting coil 55 across terminals 28, 29, operation of another switch 45 controlled by the relay effecting permanent connection of the coil 55 after the switch 18 has opened. Actuation of switch 45 allows the charging of a capacitor 40 through a resistance 41 so that after a predetermined time a neon bulb 42 is lit and its illumination alters the resistance of a photo-electric cell 56 to de-energize the coil 55 and open switches 25, 45. Upon expiration of the cooking period, which may be selected by a push-button timer, the oven door is opened and closed, thereby actuating the switch 18 to short-circuit the capacitor 40 and thus reset the timing circuit, which thereupon operates as described above to maintain the magnetron filament energized for the predetermined time. Such resetting also occurs if the oven door is operated before the expiration of the cooking period or the predetermined period subsequent thereto. In a modification, Fig. 3 (not shown), the capacitor 40 is short-circuited by a switch controlled by a second relay coil connected between the rectifier 36 and a fixed contact of the switch 18. Alternatively, the second relay coil may form one arm of a bridge network across whose output is connected to the first relay coil, the switch 18 having only two fixed contacts, Fig. 4 (not shown). In another modification of the circuit of Fig. 2, the switch 18 comprises a conductive slide which is reciprocated in response to movement of the oven door and connected so that the capacitor 40 is short-circuited by operation of the switch 45 upon de-energization of the relay coil 55, Fig. 5 (not shown).

Filed: 1975-12-03
Abstract: 1530305 Blow moulding oriented articles CARNAUD TOTAL INTERPLASTIC 3 Dec 1975 [4 Dec 1974] 49649/75 Heading B5A  An oriented hollow body of a polyester is blow moulded from an amorphous preform at a temperature from 0-30 C. above the glass transition temperature. The preform itself is blow moulded from a hot extruded or injected parison in a cold mould. The blow moulded body may be cooled to solidify it and then heated, perhaps by a hot liquid to be packaged in the body, to stress-relieve it. It is preferred for the preform to have a detachable section by which it can be held during the blowing and for even the neck portion of the blown article to be oriented. In the embodiment of Fig. 1 blown preforms 3, rendered amorphous by rapid cooling, are formed in a device 2 from a parison extruded by extruder 1. The parisons are fed to a store 6 and are thence passed through a heating oven 7 on a conveyer 8 which has facility for rotating the preforms. The heated preforms are fed to a blow mould and blown into bottles 11, 13. Each preform 5 comprises a body section D1, a so-called "false-collar" D2, and a so-called "drop" D3 which is severed from the preform by a blade 4 before storage. The blow mould 14 includes a section 19 accommodating the false collar, a neck forming section 18, separated by a knife edge 20 from the section 19 and in which the upper part of the section D1 of the preform is expanded, and a body forming section. Prior to blowing through a conduit 17 in a supporting mandrel, the preform is stretched by a section 16 of the mandrel. The false collar is subsequently severed from the blown container.
